Health problems that senior cats may encounter:
1. Older cats are more prone to problems such as arthritis, obesity, vision and hearing loss, and dementia.
2. It may also lead to diabetes, cancer, kidney or liver disease, and thyroid problems.
3. Dental problems are also common in older cats, such as gum disease and root resorption (a disease in which the roots of teeth dissolve). 
Precautions for cats as they age:
1. Adjust their diet: As cats age, they gradually lose protein, so older cats need significantly more protein than younger cats. In addition, due to the lack of exercise in older cats, pay more attention to the firmness of their food, supplement with appropriate amounts of calcium, iron, vitamins, and other trace elements, and offer a variety of flavorful foods.
2. Regular cleaning and grooming: Senior cats tend to be dirtier due to their limited mobility and lack of energy. Pet owners should regularly groom their cats' fur, brush their fur, trim their nails, and clean their eyes, ears, mouth, and nose to provide them with a clean and comfortable environment.
3. Spend more time with them: Cats entering old age are essentially nearing the end of their lives. No matter how much longer they have left to live, all we can offer is companionship. Spend as much time as possible by their side, let them feel our love, and let them enjoy their later years in peace.
